## Summary

The abp-next-admin software, a multi-tenant administration framework, is affected by a flaw in its file download feature that lets logged-in users access files belonging to other tenants. An attacker can exploit the bypass to read another tenant's stored files, compromising the confidentiality of that tenant's data.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- colinin abp-next-admin: from 10.4.0, through 10.7.0

## Description

abp-next-admin 10.4.0 through 10.7.0 contains a cross-tenant authorization bypass in the BlobManagement download-by-name endpoint, letting authenticated users read other tenants' files. Attackers supply a victim tenantId in the request path, causing DownloadByNameAsync to switch tenant context and return blobs stored by that tenant.
